The Enchantment of the Seas returned to Baltimore early Monday morning after a man found his 62-year-old wife dead inside their stateroom sometime on Sunday. She wasidentified Thursday as Katherine Kennedy.

Officials said an autopsy confirmed Kennedy died from heart disease and that her death was classified as a natural death.

The seven-night cruise sailed from Baltimore to Port Canaveral, Fla., and then went on to Nassau and Cococay in the Bahamas.
